what is a 2-11 alarm? in fire department lingo?

Answer:

Red fire hydrants are more limited in their performance ability because of their lack of a large diameter hose connection. That is if it is a private fire hydrant.
Cause thats what the city decided to paint them
Because hydrant colors communicate different messages to firefighters. They have to know what length hose to connect and the pressure there. Also, doing so makes it easy to recognize by firefighters. This helps BEFORE and DURING a fire which reduces search time. When firefighters are driving around the city to see their response times, they can become familiar with the locations making it easier to locate during a call. I hope that helps.
